Thread evaporation
There was a thread started on here on the day of the incident, but it strangely seems to have evaporated.
As it happens, I drove past the site 10 or 15 minutes after the event and the fire service were in attendance and there was a blue and yellow helicopter overhead. Weather was nil wind, mist with some thicker patches and very humid. I imagine the pilot was hoping to make Bicester which is only a short distance away, but the lorry park has a line of trees around one edge.
Thankfully, all on board survived.
